Description
Technical field
The present invention relates to a kind of track construction method of urban track traffic, be specifically related to a kind of job practices that realizes rail location and assisting in reducing running noises.
Background technology
Noise is the pollution sources of environment, and is very harmful to the health of human body, and each state is all strengthening the dynamics of administering noise.At present, train constantly raises speed, and causes at the wheel track noise in rising trend along with the raising of train speed.The wheel track noise is the main sound source of train when the following speed of 250km/h, and rail vibration is the main cause that produces noise.This not only makes the passenger be fed up with, and especially night, influences passenger's rest, brings adverse influence also for the application life of train and end of rail, has shortened the application life of rail.
The preventing of the operation noise of current track traffic train mainly contains: noise abatement measures such as sound barrier, sound proof window; Carry out Noise Prevention and Treatment from the route of transmission; Be engaged in personnel to the maintenance of circuit, work progress complicacy simultaneously and the construction cost of sound barrier is high, the cycle is long, influence the worker; The expense that wastes time and energy is artificial, and the noise reduction of sound barrier also received the influence of track apart from the distance of barrier, is difficult to satisfy the application demand under the various environment.Rail noise controller is as a kind of novel track noise control technique of track noise control; Can there be following defective: adopt sandwich construction, on the web of the rail and the rail wing, be stained with the multilayer amortization from the angle control train operation noise of sound source; Damping layer is changed difficulty, and application life is short; Simply noise reduction in the structure can not played effect for the location of rail, and installation process is complicated, needs the manual work of labor, and investment is big, and application life is short.
Summary of the invention
Is that the noise that produces is big in order to solve present track train in operation; Pollute, influence the problem in the application life of rail simultaneously, and the construction cost of the noise control measure of track train now is high; Can not satisfy the shortcoming of all-environment application demand; And the noise control service life of equipment of existing rail is short, can not play the effect of assist location, the shortcoming that installation process wastes time and energy to rail; The present invention proposes a kind of simple mounting method; The technical scheme that adopts is: a kind of job practices that realizes rail location and assisting in reducing running noises, and realize by additional positioner by means of between rail and sleeper, being provided with for this method, it is characterized in that step is following:
1), chooses supporting damping clamping plate and locating support idol part according to the physical dimension of the rail web of the rail;
2), supporting subbolster is set between the bearing plate bars on rail and the sleeper, the height of adjustment rail adheres to specification;
3), the rubber tile in the location structure of noise abatement is close to the web of the rail place of rail both sides, by the locating slot location rubber backboard in the rubber tile outside;
4), the fin on the positioning panel in the locating support is pressed in the groove on the rubber backboard realizes that support is connected with the spacing of damping clamping plate;
5), the base plate in the locating support is enclosed within on the stone bolt of sleeper and be arranged in the sleeper groove, foot bolt securely, through the spring secures rail to sleeper locating support will be fixed on the sleeper, the side of rail.
The invention has the beneficial effects as follows: use fagging formula rail noise-decreasing device; The groove of noise-decreasing device location rail adopts bipeltate to absorb the noise that rail produces, and has also played the effect of rail rail brace part simultaneously; Help the safe operation of train, prolonged the application life of rail.The inventive method is simple, and construction has reduced the noise of train when rail running easily, has reduced noise pollution.Improve the safety of safe train operation, increased the application life of rail.

The specific embodiment
Referring to accompanying drawing, the technical scheme that the present invention adopts is: a kind of job practices that realizes rail location and assisting in reducing running noises, and realize by additional positioner by means of between rail and sleeper, being provided with for this method, step is following:
1), chooses supporting damping clamping plate and locating support 6 even parts according to the physical dimension of rail 1 web of the rail;
2), supporting subbolster 12 is set between the bearing plate bars on rail 1 and the sleeper 4, the height of adjustment rail 1 adheres to specification;
3), the rubber tile in the location structure of noise abatement 2 is close to the web of the rail place of rail 1 both sides, by the locating slot location rubber backboard 3 in rubber tile 2 outsides;
4), the fin on the positioning panel in the locating support 67 13 is pressed in the groove on the rubber backboard 3 realizes that support is connected with the spacing of damping clamping plate;
5), the base plate 10 in the locating support 6 is enclosed within on the stone bolt 8 of sleeper 11 and be arranged in the sleeper groove, fastening bolt 8, through spring secures rail to sleeper 9 locating supports 6 be fixed on the sleeper, the side of rail.
